WATCHMAKERS TOOL.

miente.

T0 all whom it may concern Be it known that l, Jose ri W. W'oonann, a. citizen of the United States, residing at TWashington, in the listrict of Columbia, have invented certain new and useful lmprovements in lVatehmakers rfools; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art 'to which it appertains to lmake and use the same.

This invention relates to new and useful improvements in watchmakers tools and more particularly to a jewelers chuck for holding watch jewels and other parts of a watch when working thereon, and the primary object of the invention is to provide a chuck which may be quickly and readily adjusted to accommodate jewels and other parts of a watch of various sizes.

er further object of the invention resides in providing a chuck which will be auto-matically locked in any position to which the same is adjusted, and a still further object resides in providing a chuck of such construction that the jaws thereof may be quickly and readily removed and other jaws interchanged therewith with little or no difficulty.

Still another object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture, and one which will be very etlicient and useful in operation.

With these and other objects in view,'my invention consists in the novel features of construction, combination and arrangement of parts, as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming part of this application: Figure l is a side elevation of a chuck constructed in accordance with my invention; Fig. Q is a top plan view thereof disclosing` the jaws in their closed and effective positions; Fig. 3 is a similar view showing the jaws in their open or inoperative positions; Fig. 4t is a bottom plan view of the device positioned as in Fig. Fig. 5 is a similar view of the device positioned as in Fig. 3; Fig. 6 is a horizontal section through the device as seen on line 6 6 ofFig. l; Fig. 7 is a bottom plan view of the device with the operating member for the jaws removed; Fig. 8 is a similar view of Speeieation of Letters Patent.

toe operating` member removed from the device; Fig. 9 is an enlarged vertical section through the complete device disclosing the jaws in their closed positions; Fig. l0 is a side elevation of a slightly diiferent form of jaw adapted to be substituted for the jaws shown in the other views; and Fig. 11 is a perspective View thereof.

ln describing the invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in whichl indicates a head member of disk-like formation provided with a central depending shank or stem 2, the upper face of said disk-like head 1 being provided with a pair of diametrical intersecting grooves 3. These grooves extend in plates at right angles to one another and provide substantially radial channels or grooves in which jaws are adapted to operate, as will be hereinafter and more particularly set forth.

Mounted to slide in the substantially radial grooves 3 are the jaws t which are plate-like in formation, fitting well between the walls of said grooves 3, and the inner opposed ends or the engaging portions thereof are increased in thickness or provided with projections on the upper faces thereof, as shown at 5. rlhe outer edges or faces of the increased portions 5 of said jaws are grooved as shown at 6 for a pur pose to be nereinafter set forth, and the inner opposed ends of the jaws have the side faces thereof beveled, whereby vto fit snugly and firmly against one another when dis posed to their innermost positions. The upper face of each jaw at its effective engaging end is somewhat odset to provide a seat 7 for the reception of a jewel setting or jewel proper to be held between said jaws. ln order to retain these aws 3 in position in the grooves of each head l, a cap member 8 is provided, the same being of disklike formation to entirely cover said head l and the same is provided with a depending annular flange 9. This flange encircles the head or base l and when said cap is properly applied, the lower peripheral edge of said flange lits flush with the under face of said head l. This cap member.is secured in position on the head` by means of set screws l0 which extend through openings in said cap member and engage threaded openings in the base or head l.

operation, assuming that the device is coripleteljT set up and the jews disposed in heir closed positions, should it be desired o apply s j ewel to his chuck, the operator engages the neil of one {ingerwith the depending stud 2O on the spring puwl 19, and draws outwardly thereon, to disengzige this poul 'troni the atchet teeth 1S. lilith the ting of the other hand? the sleeve lli is partially rotated couliter-clockwise on the stein 2. 1in 'View of the particular construction described shove and clearljY disclosed in the drawing, will he seen that such nioveinent of the sleeve will dispose seid jews to their extended or open positions. 'I he jews will he liinited in their outward inovenient by the engagement of the inner jgieriphersl edge of the esp ineinlier 8 with the inner wells of the grooves in said j uws, and the jewel indy then he properlj7 applied in the space between seid jaw member". When the jewel is properljT positioned hetween the jew members, the sleeve le is rotated clockwise, on the stein 2, which will cause the jaws to `he disposed inwardly to grasp the jewel. its stated, the inward increment of the Ci-ws will position the saine for engagement with the jewel setting or jewel proper which is designed to be reto provide tlie in the drewin i o jew isti v not be rotated in the op` ceived in ther seats provided therefor in the upper faces ofl said jaws. V17 hen the jaws are effectively engaged with the jewel, the same will be securely held in position by the engagement of the spring pawl 19 with the ratchet teeth 18, and said jaws will not be adapted for casual disengagement. Ilhe chuck may then be applied in a vise or de` vice for holding the same, and the jewel held in position to be operated upon by the watchmaler.

Should it be desired at any time to interchange the jaws of the device, it is only necessary to dispose the jaws already in the device to their closed positions, whereupon he set screws 10 are disengaged and the cap or cover 8 removed. The jaws l may then be readily removed from the grooves in the head or disk 1 and the jaws 21 substituted therefor. rlhe cap member may be then replaced to its position and the device is then ready for use. In view of the stepped projections 2B provided on -the jaws, it will be seen that wheels of various sizes may be held therebetween and in addition thereto, these jaws are capable of the adjustments of which the first mentioned jaws are capable.

From the foregoing, it will be seen that l have provided a simple, inexpensive, and ethcient means for carrying out the objects of the invention, and while it have particularlj.T described the elements best adaptedto perform the functions set forth, it is obvious that various changes in form, proportion, and in the minor details of construction ma y be resorted to without departing from the spirit or sacrificing any of the princip es of the invention.
